0:00 Open.
0:17 Hello & welcome.
0:37 Dr. Joscha Bach bio and introduction.
0:56 “It’s an insane world; an amazing time to be alive“
3:46 Conversation on the S-curve; current instability based on not handling aftermath of collapse of Industrial Revolution society with the advent of the Internet.
8:22 “Either kids or long-term civilization”; carbon sequestration involves not burning any carbon at all.
10:08 Organizing principles conflict with systems bent on infinite growth.
14:30 More on Dr. Bach at Cambridge; entrepreneurial journey leads to MIT and then AI Foundation.
16:23 Relationship between the physical world and our minds; pattern generation; types of computers.
18:10 Mathematics vs. Computation.
19:20 Accidental question-Dr. Bach’s thoughts on psychedelics.
20:27 Turing, “something is true if you can prove it“
23:14 Quantum computing discussion; Minecraft CPU example; “is our universe efficiently implemented or inefficiently implemented?“
23:50 Relationship between mind and universe; observational interface.
27:28 Materialism and idealism may complement each other.
29:08 Dream space neural architecture; “you and me are characters in a multimedia novel being authored by the brain”; the collective is part of your dream.
31:51 Necessity of ability to change the way you perceive vs. changing a physical world; perception upgrade is really a will or desire upgrade.
34:12 What is a model? Perspectives of variables and their relationship; probabilities.
35:58 Model convergence to truth aided by probabilities; motivations guide preferences.
38:00 People are born with ideas and then acquire preferences; motivation is how you regulate and push against reality; feedback loop from brain regulating body, awareness and unawareness of loops.
41:28 Needs don’t form a hierarchy; they coexist and compete.
43:00 “the shape of your soul is the hierarchy of your purposes“
45:26 Neurons; dopamine and other brain chemicals speak many languages; “neurons get fed if you regulate what you want to regulate“
48:50 Social interaction and brain chemistry; neurons work through pattern recognition, then patterns in the patterns.
51:43 Auditory (and all) senses build layers until we get a unified model of the world/universe.
53:24 Question-who’s in charge of the super-intelligence; single mind; which kind of system; sane/insane implementation.
59:50 Precepts; spatial intelligence; pattern to perception to worldview; intentional self.
1:02:36 Self controls simulations in the brain; “only a simulation can be conscious“
1:05:05 “The reason why you perceive the world as meaningful is because it’s generated in your mind to model your meaning.“
1:07:10 Everything you can perceive is generated by your mind; model of architecture.
1:11:45 Use of the DLPFC (dorsolateral prefrontal cortex); “hippocampus has a script”; neurons individually not that important, somewhat interchangeable, just a signal processor.
1:14:52 “Are we individually intelligent?” Not generally so; generations of specialized people talked to each other; rebuilding efforts usually get foundations wrong; “it’s hard to wake a sleeping person; it’s impossible to wake a person pretending to sleep“
1:17:52 “The family of good people” is a human condition; morals need to guide our decisions but not our model-making.
1:19:00 Human-centric social media; scientists and philosophers are mostly confused people, humble but without answers; Dunning-Kruger Effect.
1:20:40 More on social media; understanding the nature of reality; “which way can I be useful to other people?”; why are we drawn to things that don’t have utility, like politics on current social media.
1:24:20 Social media done right are individual thoughts in the same mind, “Gaia doesn’t exist but it would be very useful to have one”; endgame of social media is a global brain.
1:26:15 Current society optimized for short games; “tumors“
1:29:02 Lebowski Theorem — “No super-intelligent system is going to do anything that is harder than hacking its own reward function“
1:31:12 “Imagine you build an AI that is way smarter, why SHOULD it serve us?“
1:32:20 “Maybe our motivational function is wrapped up in a big ball of stupid so we don’t debug it;” opting out of reality; how can we balance super-intelligence, will, and evolution or conditions of existence.
1:34:08 Philosophical remarks; reiteration that things are just happening, making it very difficult to predict outcomes; there isn’t a running simulation of a better society so it’s difficult to make changes.
1:36:15 Life is about cells, and cells are very rare.
1:38:08 Would have to be a larger, more imperceptible pattern around us and how would we know; Minecraft example.
